The Laser Logical Gates

Abstract

Theresearchproduceatheoreticalstudyfordesigningnewlogicalgates based on laser source. As known 1'et, the design of the processordepends of logical gates, rvhich represent the basic component of itsarchitecture. The speed ofthe processor depends on how the layout designsofthelogicalelectroniccircuit(processorarchitecture),anddependonthespeedoftlreelectricalsignaltravelingtlrroughofthegates.Since,thebasicelementsofthegatesarenranufacturedfiornasemiconductormaterials,tlrentheelectricalsignalspassestlrrouglritneedsacertaintimewhichconsiderveryshortforasirrglegatebutitisnoticedforoveralltheprocessor chip.
